Applied Parameters: Action = Apply|Index=n (where n is in the range 1 to 8)
This command is used to apply a filter to the current document, essentially using the content of the indicated selection memory location as its scope.
The related indexed command can be accessed from the PCB Editor by:
- Choosing the Edit » Selection Memory » Apply » n command, from the main menus.
- Using the Shift+Ctrl+n keyboard shortcut.
- Clicking the Apply button, associated with memory location n, in the Selection Memory dialog.
After launching the command, filtering will be applied based on the content of the indicated selection memory location. The visual result of the applied filtering in the main design workspace is determined by a series of controls, defined at the bottom of the Selection Memory dialog:
- Mask - the filtered objects will appear fully visible in the workspace, with all other objects becoming dimmed. With masking applied, all objects not under the scope of the filter will be unavailable for selection/editing.
- Select - the filtered objects will be selected in the workspace.
- Zoom - the filtered objects will be zoomed and centered (where possible) in the workspace.
Any combination of these options can be enabled. For example, you might want to have all filtered objects zoomed, centered and selected in the main design window, whilst applying masking to take away the clutter of other design objects.
The Clear Existing option, also in the dialog, enables you to extend an existing filter, essentially refining the filter further by applying a new filter in addition to the existing one. To do this, make sure this option is disabled. If it is enabled (default) the existing filter will be cleared before applying the new one.
- You can control all aspects of the selection memory feature from the Selection Memory dialog. This dialog is accessed by using the Ctrl+Q keyboard shortcut. As well as providing controls for manipulating each of the eight available selection memory locations, the dialog also summarizes the content status of each location. Selection content is summarized in terms of quantity of specific object (if the selection contains objects of a single type) or total number of objects (if the selected objects are of differing types).
- With masking applied, all objects not under the filter scope will be unavailable for selection/editing. The extent of the masking applied can be manually adjusted using the Masked Objects slider bar, accessed in the Mask and Dim Settings section of the Layers And Colors panel.
- You can manually clear an existing (and applied) filter at any time by using the Shift+C keyboard shortcut, or by clicking the button in the Selection Memory dialog.
